Title: Improvements in or relating to indicating devices
IPC: G01L19/08
Filed: 1929-06-18
Abstract: 331,370. Griffith, A. A., and Lockspeiser, B. June 18, 1929. Elastic-diaphragm pressure gauges; indicating- means for. - A pressure-indicating device comprises two parallel strips A B, C D joined together at the ends B, D, the end C of one strip being attached to the support while the end A of the other strip has applied to it along the axis of the strip the pressure to be measured. In the form shown in Fig. 1, a capsule is formed at the end of a silica tube Z a portion of the wall of the capsule being formed as a thin diaphragm X, Y, to which a silica strip A B is attached. The parts A B, C D and the support W are all made of silica. Fused to the bridge piece B D is a pointer L which carries at right angles to its length an arm G E also of silica the ends of which are connected by silica fibres to a second arm H F parallel to the first on the stem of the capsule. The arrangement is such that the two-fibres and the strip C D are in the same plane when the strips are undefleoted. The pressure fluid is conveyed through the stem Z. and the movement of the diaphragm causes the pointer to move clockwise. The structure may be mounted in a case which may be evacuated, the deflection of the pointer being observed through a silica window by means of a miscroscope. With the case evacuated, the device is suitable for measuring absolute pressures, otherwise it is suitable for use as a null instrument. In another form, the structure as above described is duplicated so that the measurement of the prssure is indicated by the degree of separation of two pointers. These may be ioined by a fibre, and the sag of the fibre observed. The device is particularly suitable for measuring small pressures such as the vapour pressures of solids.

Title: Improvements in and relating to carburettors for internal combustion engines
IPC: F02M21/00
Filed: 1935-07-01
Abstract: 448,363. Spray carburetters. CHASE, W. O., 18981, Farmington Avenue, Detroit, Michigan, U.S.A. July 1, 1935, No. 18798. Convention date, June 30, 1934. [Class 7 (iii)] A carburetter comprises an air entrance having an air valve therein, a mixing chamber leading therefrom, a fuel passage leading to the chamber from a source of fuel supply, a second air entrance connected by a passage to the chamber, the flow of air through this passage being adapted to open the air valve, and means responsive to a decrease in the level of the fuel in the supply source for progressively closing the second air entrance. Within the main air inlet 11 a bridge piece 13 supports an apertured choke valve 15 for starting and a cylindrical valve 12 displaceable in the bridgepiece 13 controls outlets 34, 35, for a fuel emulsion, and an air passage, through a ring 105, on either side of the bridge piece. Fuel is supplied to the outlets 34, 35 from a chamber 67 into which fuel is drawn past a valve 86 supported by a diaphragm 70 open to the atmosphere on its upper side. Normally, suction draws the fuel into a central chamber 88, through ports 90 into the chamber 67, past a check valve 65 through a passage 41 to a piston 101. A flap valve 42 in the piston passes the fuel through ports 44 to a tapered annular space 45 leading to a passage 46 connected to a passage 26 in a bridgepiece 99 across the air inlet. The passage 26 leads to a conical opening 24 housing a disc 22 on the stem 21 of the air valve 12. Alternatively, the fuel may reach the passage 26 through ducts 60 in the piston 101, passages in a plug 103 through which the piston rod 102 moves, a port 53 and a passage 51. The piston 101 is connected to the throttle valve 31, and also provides fuel for acceleration through this second channel. At its lowest position, the piston cuts off the passage 46 and fuel for idling traverses the second channel to a passage 28, air being drawn down a passage 58 from the air inlet and through ducts 56 in the plug 103 to the port 53. A disc 23 below the disc 22 on the valve stem 21 is disposed in a lower conical opening 25 to which air is supplied through a port 38 and passage 37, there being a similar port 48 in the passage 26. Air for these ports is drawn from a passage 71 leading to a valve 73 controlled by the diaphragm 70, depression of which, due to a lowering of the fuel level at the source of supply, reduces the air passage. According to the position of a slide valve 40, adapted to be raised by opening of the throttle, air is drawn along a passage 75, the chamber 104 of the valve 40<1>, a port 50, passage 49 and the port 48 to the passage 26 or along the passage 75, a byepass 76, the lower end 40 of the chamber 104, a port 39 to the passage and port 38. In either case, restriction of the air supply through depression of the diaphragm 70 reduces the upward flow of fluid past the discs 22, 23 and the air valve 12 moves towards closure and corrects the mixture.

Abstract: 586,513. Code telegraphy. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 18, 1943, No. 19304. Convention date, Nov. 19, 1942. [Class 40 (iii)] To regenerate telegraph signals., two. trains of pulses of baud frequency are produced, one train being applied continuously to a repeater having 'two conditions of stability to urge the repeater to one of the conditions, and the other train being applied during signal marks to urge the repeater into its other condition of stability and to predominate over the other pulses, thereby effecting the repetition of the regenerated signals. In the arrangement described, baud frequency pulses are produced and corrected as to phase with relation to the received signals in the manner described in Specification 586,547. The phase-corrected pulses are fed via transformer 151, Fig. 2, with adjustable phase shift to amplifier 154, which feeds a limiter-amplifier, J 55 producing square Wave pulses which charge condensers 158 and 162 in parallel. The time constant of the discharge circuit of 162 is greater than that of 158. Pulses from 162 are applied to a valve 164 which has received signals applied to it via 167 and is biassed so as to be blocked during spaces and just conducting during marks. Pulses from condenser 158 are applied' to a valve. 161 which is normally blocked but passes positive pulses. Condensers 182, 185 are arranged to be discharged through valves 161, 164 and diodes 183, 186 when valves 161, 164 become fully conducting, to control the action of the two position. repeater 174. This is tripped in one direction during spaces by the pulses fed via valve 161 and in the other direction during marks by pulses fed through tube 164, the latter pulses having greater duration than those fed via 161 and so controlling the repeater, the output 179 of which actuates a contact making relay to produce the regenerated signals.

Abstract: 495,495. Converting. GENERAL ELECTRIC CO., Ltd., and PRINZ, D. G. July 13, 1937, No. 19395. [Class 38 (ii)] In a converter comprising valves having mercury cathodes on which a cathodic spot is initiated at a selected point in each conductive half cycle by applying impulses to an ignition electrode, the effects of misfiring in a single valve are avoided by using in place of a single valve a pair of valves in parallel and supplying them with substantially simultaneous ignition impulses. The valves may have such relative starting and running voltages that if the main valve fires, the auxiliary valve is prevented from firing, preference being given to the main valve by causing its ignition impulses to lead slightly on the ignition impulses applied to the auxiliary valve. Alternatively the auxiliary valve may be given preference in firing, the arrangement being such however that it only continues to conduct if the main valve fails to ignite. A battery may be connected in series with the auxiliary valve to determine preference in firing instead of using valves with different voltage drop. U.S.A. Specification 2,005,875 is referred to. Reference has been directed by the Comptroller to British Specifications 387,186 and 474,061.
